You are now leaving the National Database for Autism Research (NDAR) web site to go to:

The filters you have selected from various query interfaces will be stored here, in the 'Filter Cart'.
The database will be queried using filters added to your 'Filter Cart', when multiple filters are
defined, each will be executed using 'AND' logic, so with each filter that is applied the result set gets smaller.

From the 'Filter Cart' you can inspect each of the filters that have been defined, and you also
have the option to remove filters. The 'Filter Cart' itself will display the number of filters
applied along with the number of subjects that are identified by the combination of those filters.
For example a GUID filter with two subjects, followed by a GUID filter for just one of those subjects
would return only data for the subject that is in both GUID filters.

If you have a question about the filter cart, or underlying filters please contact the help desk at
The NDA Help Desk

Age is rounded to chronological month. If the research participant is 15-days-old at time of interview, the appropriate value would be 0 months. If the participant is 16-days-old, the value would be 1 month.

This page displays the data structure defined for the measure identified in the
title and structure short name. The table below displays a list of data elements
in this structure (also called variables) and the following information:

Required: This column displays whether the element is Required for valid submissions,
Recommended for valid submissions, Conditional on other elements, or Optional

Description: A basic description

Value Range: Which values can appear validly in this element (case sensitive for strings)

Notes: Expanded description or notes on coding of values

Aliases: A list of currently supported Aliases (alternate element names)

For valid elements with shared data, on the far left is a Filter button you can use to
view a summary of shared data for that element and apply a query filter to your Cart
based on selected value ranges

At the top of this page you can also:

Use the search bar to filter the elements displayed. This will not filter on the Size of Required columns

Filters enable researchers to view the
data shared in NDA before applying for access or for selecting
specific data for download or NDA Study assignment. For those with
access to NDA shared data, you may select specific values to be
included by selecting an individual bar chart item or by selecting a
range of values (e.g. interview_age) using the "Add Range" button.
Note that not all elements have appropriately distinct values like
comments and subjectkey and are not available for filtering.
Additionally, item level detail is not always provided by the
research community as indicated by the number of null values given.

Filters for multiple data elements within
a structure are supported. Selections across multiple data structures
will be supported in a future version of NDA.
